Sudoku

Classic 9x9 logic puzzle. Place digits 1-9 so every row, column, and 3x3 box contains each number exactly once.

Combine Sudoku logic with cage sums. Fill the grid so rows, columns, and boxes are valid while each cage reaches its target total.

Math meets logic. Fill the grid with numbers that satisfy row/column uniqueness and arithmetic clues inside outlined cages.

Use only 0 and 1. Keep each row and column balanced, avoid triples, and ensure every row and column pattern is unique.
